Hard alloy VK10KS is strengthened to a depth of 15 – 20 μm by subjecting the surface to pulse plasma jets formed by electric explosion of a titanium foil together with a weighed portion of SiC. Such a treatment produces a surface layer consisting of TiC,W2C, (W, Ti)C1 – x carbides and WSi2 silicide. The surface hardness is increased to 26,000 MPa and the wear resistance is enhanced.
